}创建实体类Hello

创建Controller
import name.quanke.kotlin.chaper11_5_4.entity.Hello
import org.springframework.stereotype.Controller
import org.springframework.ui.ModelMap
import org.springframework.web.bind.annotation.ModelAttribute
import org.springframework.web.bind.annotation.PostMapping
import org.springframework.web.bind.annotation.RequestMapping
/**

*/
@Controller
class HelloController {
@RequestMapping("/")
fun index(map: ModelMap): String {
// / 加入一个属性，用来在模板中读取
map.addAttribute("host", "http://quanke.name")
map.addAttribute("hello",Hello())
// return模板文件的名称，对应src/main/resources/templates/index.html
return "index"
}
@PostMapping("/hello")
fun helloPostSubmit(@ModelAttribute hello: Hello): String {
return "result"
}
}页面展示层
